A max of 9C isn't really "winter" for continental locations which predominate north of 40N latitude. It's more like November and March. Also a summer max of 22C is closer to a temperature most continental locations experience in the after midnight hours. Most in continental climates would call it late spring or mid fall weather.... And is in no way "summer like" to anyone who is used to a continental climate, subtropical climate, tropical climate, or desert climate....

22c at night is hell like !! But during the day it is lovely, and being an island the weather can be quite humid, so out of the wind 22c would probably feel more like 27c or something, and with reasonable sunshine avs it may feel slightly higher than that...
^^
Outside the tundra and the higher latitudes 22C isn't even close to being considered summer. As for humidity, the UK's climate doesn't produce heat indecies that often. In fact an air temperature below 27C cannot produce a heat index no matter how humid it is...
I think Portsmouth averages about 75-80% humidity in summer.
If you look at this Humidex, 22c in 75% humidity = 27c... Though still comfortable weather.
That's the over inflated humidex formula... I bet it would have read over 40C today in Chicago (actually, I just did it.... 39C was the high humidex today)
A 75% humidity wouldn't normally come at the peak hours of heat in Portsmouth (more like evening or early morning) even if it did.... Look.... No heat index calculated

Maybe it doesn't calculate under 26.7c because anything lower isn't significant enough... But EuroWeather does as my box above shows.
Pleasant summers with good sunshine. Rest of the year is still too cool and dark.
